The transparent rubber sleeve 83 is fixedly connected to the lower ends of the two discharging ports of the Y-shaped three-way pipe 7, and the lower ends of the transparent rubber sleeve 83 are provided with a discharging hopper 81. The upper surfaces of the two discharging hoppers 81 are provided with a sealing plate 82. The lower surfaces of the two discharging hoppers 81 are provided with an inverted U-shaped frame 84. The interiors of the two inverted U-shaped frames 84 are fixedly connected with evenly distributed connecting plates 86 by mounting bolts. The lower ends of every three connecting plates 86 located on the same side are also fixedly connected with a vibration isolator 4 by mounting bolts. The two vibration isolators 4 are fixedly connected to the lower inner wall of the bracket. It also includes a blocking gate body 2, and the blocking gate body 2 is respectively provided with The telescopic ends of the blocking gate body 2 are provided with plugging heads on the left side of the upper surface of the left sealing plate 82 and on the right side of the upper surface of the right sealing plate 82, the left side of the lower surface of the discharge hopper 81 is provided with a discharge port 3 on the left side, and the right side of the lower surface of the discharge hopper 81 is provided with a discharge port 3.

When the remote controller transmits data back through the weighing sensor, if the current hopper body 1 loses weight due to the transportation of solid materials to the discharge port 3, it is compared with the weight before the start of feeding. When it is concluded that the preset batch weight has been reached, the blocking gate 2 will act to block the discharge port 3 to complete the current batch feeding action.

[0018] The working principle of a controller for feeding bulk solids using a pneumatic vibrator provided by the present invention is as follows: the weightless gas vibrating feeder can be installed on a designated workstation through three support plates, and bulk solid materials are put into the hopper body 1 through a manual feeding port. The materials are respectively collected into two discharge hoppers 81 through a Y-shaped three-way pipe 7. At this time, the blocking gate body 2 blocks the discharge port 3, and the weighing sensor in the hopper mounting base 5 records the weight of the materials put into the hopper body 1 in real time, and converts the information into an electrical signal and returns it to the single-chip microcomputer 10 in real time. The single-chip microcomputer 10 issues a feeding instruction and sets the batch weight, and can regulate and select one of the two appropriate vibrating discharge bodies 5. Select one of the two appropriate vibrating discharge bodies 5, and cancel the blockage of the plugging head, and the air compressor can be regulated. The upper air vibrator 6 is in operation, and after ventilation, the air vibrator 6 vibrates at a certain frequency, and the air compressor can be regulated at the same time. The lower air vibrator 87 is also in operation, and after ventilation, the lower air vibrator 87 vibrates at a certain frequency. At this time, the discharge hopper 81 is tilted and is also affected by the amplitude. The compressed gas pressure is adjusted to control the solid material conveying speed. When the upper and lower air vibrators 6 and 87 are working, in order not to affect the hopper body 1, the vibration isolator 4 uses a steel wire rope in series to connect the skeleton to achieve 360 ​​degrees of force to reduce vibration transmission. When the remote controller transmits data back through the weighing sensor, if the current hopper body 1 loses weight due to the transportation of solid materials to the discharge port 3, it is compared with the weight before the start of feeding. When it is concluded that the preset batch weight has been reached, the blocking gate 2 is actuated to block the discharge port 3 to complete the current batch feeding action.

[0019] It is worth noting that the single chip microcomputer 10 disclosed in the above embodiment is specifically model S7-200, and the blocking gate body 2, the vibration isolator 4, the upper air vibrator 6, the lower air vibrator 87 and the weighing sensor 9 can be freely configured according to the actual application scenario.
